Title: Biologically-active materials
IPC: C08L21/00
Filed: 1975-01-17
Abstract: A preparation for the controlled release of an effective amount of a biologically active material to the environment is composed of an intimate mixture of an organic polymer and a biologically active material, for example a pesticide; the mixture releases the biologically active material to the environment by molecular diffusion through the polymer matrix at the surfaces exposed to the environment, and the polymer contains a sufficient amount of the biologically active material that, when the preparation is exposed to the environment, the biologically active material diffuses into the environment and the polymer subsequently loses its structural integrity at the surfaces which are exposed to the environment; this causes fresh surfaces of the preparation to be exposed to the environment, and an effective amount of more biologically active material is released over a substantial period. The preparation is particularly suitable for the long-term supply of effective amounts of pesticide to crop plants. Fig. 1 shows the release rate of the active substance in a preparation according to the invention (Graph b) and of a known preparation (Graph a). <IMAGE>

Abstract: 1,139,761. Hand grenades for distributing gases. C. S. CROSS (United States of America, Army Secretary of the). 18 Jan., 1966, No. 2307/66. Heading F3A. [Also in Division A5] A hand grenade containing gas-dispersing material has a rubber casing 30 and a fuze 26 to ignite a charge 32 housed therein. Charge 32 may be black powder or other low explosive. On ignition, charge 32 disrupts the casing 30 and ejects containers 10 embedded in the charge. Each container 10 comprises a cylinder of aluminium or steel closed at each end and housing an axially bored charge 12. The bore 15 communicates with a port 14 in one end wall and in its other end is a delay mixture of silicon and red lead, which is ignited by the charge 32. When the delay burns through, it ignites the charge 12 and the residue of the delay blocks the bore at the end holding the delay, so that gases from the charge 12 issue through port 14. In a modification, the port 14 is replaced by a port (21) adjacent the delay and inclined to the bore 15, the issuing gases being deflected by a baffle (20) to force the container to travel along a curved path. The charge 12 comprises a mixture of a lachrymatory agent and combustible materials. In an example 40% o-chloro benzal malononitrile is mixed with 27% potassium chlorate, 18% sugar, 12% magnesium carbonate and 3% cellulose nitrate, the proportions being by weight. The mixture was compressed by a ram at a pressure of 1200 p.s.i.

Abstract: 1,255,356. Uses of luminescence. H. NEWBY (Badische Anilin- & Soda-Fabrik A.G.) 15 Jan., 1969, No. 2371/69. Heading C4S. [Also in Division G2] A photographic process comprises in age-wise exposing a material containing a layer of a diazonium salt and developing with a coupler to produce an azo dye image; before or after exposure or after development arranging a fluorescent dye layer over the azo dye layer so that is not more than 150 Š away and so that the fluorescence maximum is approximately the same as the absorption maximum of the azo dye and then uniformly exposing the assembly to light which excites fluorescence to produce a fluorescent image which is the reverse of the azo dye image as the azo dye extinguishes fluorescence. The invention also relates to a layer assembly comprising a support carrying a layer combining either a diazonium salt or an azo dye image formed by image-wise exposure and development of a diazonium salt and a layer containing a fluorescent dye as specified above arranged over the first layer and not more than 150 Š away. In the example, molecular layers of arachidic acid on water are applied to a glass support and similarly, molecular layers of a mixture of arachidic acid, cadmium chloride, chloroform and a diazonium salt of formula on water are applied to the support. The material is image-wise exposed and developed with a buffered solution of 8-hydroxyquinoline. A molecular layer of arachidic acid and a fluorescent cyanine dye of formula wherein X is oxygen or sulphur on water is applied to the support and the material is uniformly exposed to 3660 Š to produce a fluorescent dye image complementary to the azo dye image. The cyanine dye layer may be applied before coupling. Alternatively, a fluorescent dye image corresponding to the azo dye image may be obtained by uniformly exposing the assembly until the fluorescent dye is bleached out in the areas complementary to the dye image. The fluorescent dye layer may then be removed by coating with a film-forming material and stripping off the film thus produced.
